DRAW-BAR FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 247,392, dated September 20, 1881, Application filed July 23, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN NEILL, a citizen of the United States, resident of Denver, in the county of Arapah oe andState of Colorado, have invented a new and valuable Improvement in Draw-Heads; and I do herebydeclare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is arepresentation of a plan view of my invention. Fig. 2 is a side view, partly in section. Fig. 3 is an enlarged sectional view of the draw-head. Fig. 4 is afront view, partly in section, and Fig. 5 is a cross-section.

This invention has relation to the draft attachments or connections of railway-cars; and it consists in the construction and novel arrangement of the draw-head, the spring and spring-seat in rear of the same, and the central and lateral connecting-rods, all as hereinafter set forth.

In the accompanying drawings, the letter A designates the end sill of the frame of a car;

B, the-transverse barsin rear of the same, and O O the longitudinal beams. Between the cross-beams B B are placed the iron plates D E E represents supporting-timbers for the draw-head, which are bolted to the framingbeams O O, as indicated in the drawings. To these supporting-timbers are secured the stirrup-plates F, forming a rest and guideway for the draw-head.

G indicates the draw-head, which is designed to be located within the stirrup, and has longitudinal play. It is provided, usually, with rear shoulders or stops, a, serving to prevent the draw-bar from being disconnected from the stirrup or guide band. In the rear portion of the draw-head is formed a seat, I), which is designed to receive one end of a strong spring, 0, which is usually made in the form of a double spiral spring, as indicated in the drawings. A perforation, d, is made centrally through the rear end of the drawhead, for the passage of the central draw rod or bolt, H, having a squared head, 0, seated in a recess, g, of corresponding shape, within the draw-head.

, K represents a strong face-plate or springseat plate, which is located centrally on the front surface of the end sill,A, ofthe car-frame. This plate is provided with a central perforation, 01, for the draw rod or bolt H, and with a seat, b, around the same, for the reception of the rear end of the spring 0. Through lateral extensions 11- of this seat-plate are formed perforations 70, for the passage of the lateral connecting-rods L. The bolt H passes also through the sill or beam A, and, projecting in rear thereof, is provided with a rubber or elastic bearing, Z, and a cast-iron washer, m, having a seat for the reception of the elastic bearmg.

011 the threaded end of the bolt is placed the nut 72, and in this manner a strong but somewhat yielding connection is formed between the cross beam or sill A and the drawhead.

Through the transverse beams B B and their intermediate iron plates, D, are made perforations is, for the passage of the rear ends of the connecting-rods L, which are secured in rear of said beams by nuts 20, and are designed to extend forward therefrom to the face-plate K. In this manner a strong connection is formed between said plate, the sill A, and bolt H, and the transverse beams B and plates 0.

This draft attachment is strong, but yielding, and easily repaired. It will preserve the car, preventing jarring to a great extent in coupling. It is designed to avoid the use of continuous draw-rods or deadwood.

Having described this invention, what I I claim, and desire to secure by Letters Patent,

1. The combination, with a draw-head and spring in rear thereof, of the face-plate K, draw-rod H, elastic bearing 1, and cross beam or sill A, substantially as specified.

2. The combination, with the sill A and the transverse bars B, of thedraw-head G, its

rear spring, 0, the face-plate K, elastic bearing In testimony that I claim the above I have 10 l, the draw-rod H, and the lateral connectinghereunto subscribed my name in the presence rods L, substantially as specified. of two witnesses.

3. The combination with the sill A and the transverse bars B, having the intermediate JOHN NEILL' iron plates, D, of the supporting-timbers E, Witnesses:

stirrup F, draw-head Gr, spring 0, face-plate K, S. WILLIS FRENCH, bearing 1, and the central and lateral connect- JOSEPH SMITHAM. in g-rods, substantially as specified. l a
